Answer 2

As per the data give in the above question.

It is given that Rate of interest is 9%

Year 3 year

SI=Rs.810

We have to find the sum of money lent.

Thus, the formula of simple interest,

$SI=\frac{PRT}{100} \\SI\times 100=PRT\\\frac{SI\times 100}{RT}=P\\P=\frac{SI\times 100}{RT}$

Substitute the value in above equation we get,

$P=\frac{810\times100}{9 \times 3}$

$P=\frac{81000}{18} \\P=Rs.3000$

Hence option D is correct while option A, B and C are incorrect.
